WIRE .STBAIGHTENING AND To all whom it may concern:

Be it known that I, FRANKLIN B. SHUSTER, citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in WireStraightening and Cutting- Oif Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to wire straightening and cutting off machines; andparticularly to machines of this character constructed and adapted forstraightening and cutting large stock. In straightening and cutting tolength wire of small diameter the feed rolls run continuously, but withlarge stock, running from a half inch in diameter, or more, it isabsolutely necessary to stop the feed rolls during the operation of thecutting oif lever. As the wire is drawn from a coil mounted feeding andpreliminary straightening rolls, together with the forward feedingrolls, have a hard pull to unwind large stock from the reel and carry itthrough the rotary straightening arbor or roll straightener, and unlessthe feeding is stopped, when the cutting off lever is operated, thepressure of the incoming wire against the lever will not only retard itsmovement but will soon wear a groove in its face.

Referring to the drawings :-Figure 1 represents a side elevation of themachine; Fig. 2 is a reverse side of the standard supporting the feedingand straightening mechanism and broken view of the mechanism forward ofthe cutting off lever on line a a of Fig. 1. Fig. 3 is an enlarged frontelevation of the machine, sectional view of the guide bar, cam shaft,and large supporting pipe on l1ne b b of Fig. 1; also broken view of thecutting 03 lever, and broken view of the feed controlling or shiftinglever on line a c of Fig. 5, the rest of the feeding mechanism beingomitted; Fig. 4 is an enlarged broken view of the machine standard.cutting off lever, feed controlling lever and supporting pipe, andsectional view of the cam shaft on line d d of Fig. 3; Fig. 5 is upon areel, the rear initial CUTTING-OFF MACH-INE.

Fig. 8 is an enlarged broken side elevationpartly in section of the cam shafts, balance wheel pulley, and sectionalview of the cam for actuating the shift lever, showing the key engagedwith the balance wheel pulley; and Fig. -9 is an enlarged broken view ofthat portion of the clutch lever adapted to engage with the key.

Like letters and figures. of reference indicate like parts throughoutthe several views.

A description of the well known features of the machine will be brieflyset forth to show the relation .of my improvements thereto.

1 is the main standard or head supporting the journaled shafts 2, 3 and4 carrying the initial straightening and feed rolls 5; 6 and 7. Theseroll shafts are geared together by the pinions 8, 9 and 10 shown at Fig.5. The forward feed rolls 11 and 12, Fig. 2,

are mounted onthe shafts13 and 14, whichshafts are also geared togetherby pinions. one, 15,'being shown at Fig. 5. The feed rolls are adjustedin the usual manner by means of the screws 16 and 17 and the hand wheels18 and 19.

20 is a balance wheel pulley, formerly an ordinary driving pulley,mounted on the shaft 21 journaled in the standards 22 and 23. This shaftcarries .the gear 24 meshing with the gear 25 on the roll shaft 3. 26 isa sprocket wheel also mounted on shaft 3, and it carries the chain 27 Vto drive the sprocket wheel 28 mounted on the forward lower feed rollshaft 14, and 29 is an intermediate sprocket idler supported on thevertically adjustable standard 30.

30 is the rotary straightener.

" 31 is thecutting ofi lever mounted on the rock shaft 32, which shaftis actuated by means of the roll 33, Fig. 3, in the lower end of NBCsaid lever, engaging with the cam groove 34 of the cam'35 mounted on thecam shaft 36 journaled in the machine head and the standard 37.

38 is the guide bar whose inner end is secured to the cutting 0d leverand to. the free ends of the rock shaft arms 39, which arms are securedto the rock shaft 32 as shown. is a smaller rock or apron shaftjournaled in the upper ends of the standards 41, which standards aresupported and' se cured on the large pipe 12. This'rod 40 carries thearms 13 whose lower ends are secured to the guide bar apron -14 as seenat Fig. 3. When, therefore, the rock shaft 32 is actuated to swing thecutting ofi lever to sever the section of wire 44 in the guide bar, itwill also actuate the arms 39, which arms, contacting with the tailpiece of the collars 45; Fig. 7, mounted on rod 40, will turn said rodto open the apron and let the severed wire section drop from the guidebar. The. coiled springs 46 on rod 40 will actuate said rod in theopposite direction to return the apron to its normal position againstthe guide bar as soon as the cutting off lever retreat-s.

4:7 is a double arm clutch lever, Figs. 3, 4t and 5, journaled on theouter end of the rod 48, Fig. 5. The horizontal arm 47 of this leverengages with a. groove in the spring actuated key 49 to hold such keyback from engagement with the balance wheel pulley 50 when the cuttingofi lever is stationary.

51, Fig. 1, is a gage rod which is located 1n the groove 52, Figs. 3 and7, to determine the length of the wire sections to be, cut ed.

53 is an adjustable block secured to the outer end of the gage rod andto the trip rod 54, and 55 is a finger connected to the gage rod towhich is attached one end of the trip wire 56, while the other end ofthis wire is attached to the lower end of the vertical arm 47 of theclutch lever, so that, when the end of the incoming wire in the guidebar contacts with the inner end of the gage rod, the clutch lever 47will be actuated to release the he and, by means of its spring 6, Fig.8, a low it to engage with the contmuously running balance wheel pulley50 and actuate the cutting off lever in the usual manner. After theclutch lever has released the key 49 it will drop in readiness for theinner face of the groove f of the key to engage with the incline face ofthe lever to force the key out of engagement with the balance wheelpulley when the shaft 36 has completed one revolution.

My present improyement consists in mechanism for temporarily halting thefeeding mechanism durin the operation of cutting off a section of wire,and it applies particularly to machines built ex ressly forstraightening and cutting ofl' large stock, for which purpose the cam 57is mounted on the shaft 36. 58 is a roll carried by the shift lever59 toengage said cam. This lever is pivotally supported on the bed bracket 60as shown.

61 is a short trip lever pivoted in the bed bracket 62, and 63 is afinger in one end of this trip lever adapted to engage with the block(it on the end of the shift lever 59 and lock the lever in the positionshown at Figs. 3, 4 and 5 while the feed rolls are in operation and thewire is being fed. When, therefore, the end of the wire contacts withthe end of the gage rod in the guide bar to actuate the trip rod 5 1,both trip wires, viz., 56 and 65, will be actuated, the former torelease the key 49 and set the cam shaft in operation as beforeexplained, and the latter to actuate the trip lever 61 and release theshift lever and place it under the control of its retraotile spring 66,which spring will cause the opposite end of the shift lever to move itssleeve 59* toward the continu ously running balance wheel pulley 20 andengage the finger 67, which finger is connected with well known clutchmechanism (not shown) which stops the feed rolls. Releasing the shiftlever, as above described, will place the roll 58 of said lever againstthe straight face of the cam 5'2, and the finger '63 of the trip leverinto the position shown at Fig. 6. The said roll will run against thestraight face of the cam during the operation of the cut-ting ofi' lever31, and when said operation is finished the incline face 57 will engagethe roll and reloch the shift lever and set the feed rolls again inoperation and also bring the cutting 0d lever .31 to a state of rest.

Referring to Fig. 4, 68 is an arm secured to the same rod on which theclutch lever 4t? is journaled, and this arm $8 carries at its lower endthe housing 69 in which is located the spring pin 70 and its compressionspring 71 and the spring adjusting screw 72. The spring 73, Fig. 1, onthe trip rod 541, which spring is adjustably located between the collars74: and 75 serves to reduoe the strain or push for tripping the clutchmechanism to actuate the cutting 0d lever, and thus assist the wire whencontacting with the end of the gage rod to force the weight of all theconstituent parts out with but little resistance. The sprin 71, Fig. at,will force the horizontal arm 4 of the clutch lever into engagement withthe key or clutch pin 1-9 after the cutting off operation has beencompleted. By reason of the two springs acting in opposite, directions,the gage mechanism can be nicely balanced by the proper adjustment ofsaid springs.

The adjusting screw '16 in the lower end of arm 68 forms a stop for theclutch lever to allow its arm an to rise just far enough to release thekey or clutch pin'.. it also prevents any vibration of the clutch leverlift tea

and gage rod mechanism,

caused by the equalizing springs 73 and 71 acting in oppositedirections.

While I show my improved tripping mechanism used iniconnectionwith arotary straightener, it is equally adapted-for roll straighteners; theformer is employed where round stock is straightened and cut, while theother is used for square stock.

Having thus described my invention. what I claim is: H,

1. In awire straightening and cutting off machine of thecharacter-described, the combination with the wire feed rolls, guide barand cutting 01f lever and its actuating shaft, and a continuouslyrunning balance wheel on said shaft, of a cam on said shaft, a shiftlever adapted to be actuated by said cam, a continuously running balancewheel pulley for driving the feed rolls, a trip lever for locking theshift lever when the feed rolls are in operation, a clutch lever forlocking the cutting off lever, trip wires connecting the trip and clutchlevers so that, when the incoming wire in the guide bar contacts withthe gage rod in the guide bar, both the trip lever and clutch lever willbe concurrently actuated, the former to release the shift lever and stopthefeed rolls, and the latter to release the cutting off lever, andmeans on said cam for relocking the shift lever, and for relocking theclutch lever.

2. In a wire straightening and cutting ofi machine, the combination withwire feeding mechanism, cutting off mechanism, guide bar, gage rod,tripping mechanism connected with the gage rod, of wires connecting thetripping mechanism with the feeding and cutting off mechanisms wherebyboth the feeding and cutting oif mechanisms are simultaneously actuatedby the gage rod.

In testimony whereof I afiix my signature in presence of two witnesses.
